BK/S500-V-125-R

Fuses have been around since the late 19th century and are now a ubiquitous part of everyday life and common household items. Here we will discuss the application field and working principle of the BK/S500-V-125-R fuse.

Applications

The BK/S500-V-125-R fuse is used in many household and automotive electrical and electronic systems. It is a slow acting fuse, meaning it either opens or briefly holds current until a predetermined current is exceeded. The fuse is primarily used for add-on accessories, such as extra lights, audio/stereo components, or other components, to reduce the power draw on the original electrical system. It is also used for installations where extra space or weight need to be considered as compared to traditional circuit breakers.

Working Principle

The BK/S500-V-125-R fuse works off of the principle of current overshoot protection. It has a metal strip that is heated by the current passing through it. This heat causes the metal strip to expand, which reduces the electrical contact, thus making it unable to carry the current anymore. This protects the wiring system from any current that may be too high.For the higher power ratings, the short circuit protective devices will disconnect the circuit before the current to the short exceeds the rating of the fuse. This allows the current to be limited by the fuse rating, eliminating any potential damage that might occur to the wiring, wires, and other components.

Conclusion

The BK/S500-V-125-R fuse is an important tool for ensuring safe electrical wiring, especially in situations where extra power or weight must be considered. It works off of the principle of current overshoot protection, effectively limiting the amount of current that passes through it and preventing any damage to the electrical system.
